At least three people were killed and five wounded when a suicide attacker detonated a car bomb at a petrol station in Lebanon's Bekaa Valley near the border with Syria, a security source said.The blast occurred in the small town of Nabi Osmane, a stronghold of the Lebanese Shi'ite Muslim militant group Hezbollah, which has been targeted by similar attacks in the past year.Hezbollah is fighting alongside Syrian government forces battling a Sunni Muslim-led insurgency against President Bashar Assad, whose Alawite sect is an offshoot of Shi'ite Islam.
